public abstract class SLBuiltinNode
extends SLExpressionNode

Base class for all builtin functions. It contains the Truffle DSL annotation NodeChild that defines the function arguments.
The builtin functions are registered in SLContext.installBuiltins(). Every builtin node subclass is instantiated there, wrapped into a function, and added to the SLFunctionRegistry. This ensures that builtin functions can be called like user-defined functions; there is no special function lookup or call node for builtin functions.

Method Detail

executeGeneric

public final Object executeGeneric(com.oracle.truffle.api.frame.VirtualFrame frame)

Description copied from class: SLExpressionNode

The execute method when no specialization is possible. This is the most general case, therefore it must be provided by all subclasses.

Specified by:

executeGeneric in class SLExpressionNode

executeBoolean

public final boolean executeBoolean(com.oracle.truffle.api.frame.VirtualFrame frame)
                             throws com.oracle.truffle.api.nodes.UnexpectedResultException

Overrides:

executeBoolean in class SLExpressionNode

Throws:

com.oracle.truffle.api.nodes.UnexpectedResultException

executeLong

public final long executeLong(com.oracle.truffle.api.frame.VirtualFrame frame)
                       throws com.oracle.truffle.api.nodes.UnexpectedResultException

Overrides:

executeLong in class SLExpressionNode

Throws:

com.oracle.truffle.api.nodes.UnexpectedResultException

executeVoid

public final void executeVoid(com.oracle.truffle.api.frame.VirtualFrame frame)

Description copied from class: SLExpressionNode

When we use an expression at places where a statement is already sufficient, the return value is just discarded.

Overrides:

executeVoid in class SLExpressionNode

execute

protected abstract Object execute(com.oracle.truffle.api.frame.VirtualFrame frame)
